Defending champion Novak Djokovic overcame Stanislas Wawrinka of Switzerland to book a place in the last 8 of the Mutua Madrid Open, winning in straight sets 7-6 (5) 6-4.
Djokovic, who was amongst the players complaining about the new blue clay used for this year’s tournament, had to fight hard to win the opening set. Wawrinka held step with the world no.1 and with no breaks of serve, the set went into a tiebreak. It could have gone either way, but Djokovic found a mini break at 5-5 just before converting his first set point.
The second set brought the first break of serve, when Djokovic finally managed to convert his 8th opportunity to take Wawrinka’s serve and take a 2-1 lead. After the Swiss dropped his serve once more, he allowed Djokovic to serve for the match at 5-2. Despite Wawrinka showing some signs of recovery and staying in the match, he couldn’t avert the inavitable and the Serbian booked a quarterfinal encounter against the winner of the match between his countryman Janko Tipsarevic and Gilles Simon of France.
Earlier in the day, Verdasco upset last year’s finalist Nadal, beating him 6-3 3-6 7-5.
